ROTARY GRAIN-CLEANER.

To all whom it mag concern:

Be it known that I, CORNELIUS QUEsNELn, a citizen of the United States,and a resident of Moscow, in the county of Latah and State of Idaho,have invented an Improvement in Rotary Grain-Cleaners, of which thefollowing is a specification.

My invention is an improvement in the class of rotary grain and othersieves designed as substitutes for reciprocating or shaking sieves andscreens.

The invention is particularly embodied in the means for supporting andalso shifting or adjusting a series 'of horizontal rotary rollers, tovary the distance between them, as required for different sizes ofgrain; also in the means for automatically communicating motion from oneroller to another.

Figure 1 is a plan view of my complete grain cleaner. Fig. 2 is an endview. Fig. 3 is a vertical section on the line 33 of Fig. 1.

The rotary rollers 1 and 1 are preferably formed of wood, and eachcorrugated circumferentially or having a succession of alternatingswells and contractions. The rollers are arranged side by side paralleland in the same horizontal plane, the swells or circumferential ribs ofone roller being directly opposite the circumferential contractions orgrooves of the adjacent one. The rollers have gudgeons 2 which arejournaled at their ends in rectangular blocks 3 and 3 The latter arearranged and supported in horizontal channel bars 4, and all of them,save the front one 3*, are slidable relative to each other in thechannel bars 4. The bottom of the latter is provided with a series oflongitudinal alined slots and each of the journal blocks 3 is providedwith a pendent lug 3 which projects through and is adapted for slidingadjustment in one of such slots.

Straight levers 5 are pivoted to pendent arms 6 of the channel bars 4and positively connected with the several lugs 3 of blocks 3 by means oflinks 7 The free ends of the levers are supported by threaded bolts 8whose upper ends pass through slots in the bottoms of the channel barsand are provided with nuts 9 on the opposite sides of the bottom. forsecuring them in any vertical adjustment. by manipulating such nuts, thebolts 8 may be adjusted higher or lower'and the levers 5 will thus becorrespondingly adjusted so Specification of Letters Patent.

Application filed March 10, 1915. Serial No. 13,360.

It will now be understood that that through the' mediumof the links 7,which serve as push or pull rods, the journal blocks 3 may all beadjusted simultaneously toward or from each other and the stationarysieve 3.

A straight plied on the upper side of the journal boxes 3, 3 and clampbolts 11 pass through the same and the channel bars 4 and thus serve asmeans for clamping the upper bar 10 upon the journal blocks or lockingthem in any position to which they may be adjusted.

In practice, the front roller, whose journal boxes are not movable inthe channel bars, will be provided with a pulley or gear by which itwill be operatively connected with some form of motor.

The means for rotatively connecting all the rollers with each other areas follows: A spur gear 12 is keyed on one end of each sieve shaft 2 andbetween each two gears 12 is arranged an idler 13, the same beingmounted on the end of a link 14 that is journaled on the shaft of one oftheadjacent sieves. Thus by gravity the several idlers 13 remain in meshwith adjacent gears 1.2 and operatively connect them, whatever he theadjustment of the sieves toward or from each other. In other words, itis apparent that the pivotal connection of the links with the shafts 2of the sieves permits the idlers to rise and fall corresponding to theadjustments of the sieves relative to each other, and the rollers aretherefore all rotated simultaneously even when an adjustment is beingmade by means of the levers 5, rods 7. and bolts 8.

The grain to be cleaned is delivered by any suitable means upon therollers 1 and 1 while the latter are rotated at the required speed, andthe grain in passing down between the rollers is subjected to suchdegree of friction as to remove adhering foreign substances.

In practice, a blast of air may be delivered up between the rollers tocarry off the light material removed by friction.

What I claim is 1. A grain cleaner comprising a series of rotary membersarranged parallel and side by side, journal boxes for the shafts of thesame which are adapted for adjustment horizontally and simultaneouslytoward and from each other, and means for effecting such adjustment, thesame comprising levers pivoted beneath the rollers, rods connectinghorizontal bar 10 is shown apj us'ting the free ends of the leversvertically,

the levers with the several journal boxes of the adjustable rollers, andmeans for adas described.

r '2. In a rotary grain cleaner, the combination with a series ofrollers proper arranged parallel, boxes for the journals of the same,

parallel horizontal channel bars in which the boxes are held slidably,the boxes being provided with lugs projecting through slots in thechannel bars, and means connected with such lugs for adjusting therollers toward or from each other simultaneously, as described.

3..In a grain cleaner of the type indicated, the combination with aseries of rollers, boxes for supporting the journals of the same, gearsapplied to the ends of the journals, i adjacent gears, and links pivotedon the lers meshing with each of two journals and idlers pivoted in thefree ends of the same, as described.

4. In a grain cleaner of the type indicated, the combination withrollers arranged parallel horizontally and having central journals,boxes in which the said journals are supported, means for supporting theboxes so that they are adapted to slide toward or from each other, meansarranged below the rollers for adjusting them toward and from eachother, and means for automatically connecting them rotatively, the sameconsisting of gears mounted on the axes of the rollers, idlersmeshingwith the gears of adjacent rollers, and links pivotallysupporting the idlers, as described.
